To all whom it may concern:

Be it known that I, Louis SPIRLIN, a citizen of the United States, and a resident of New York, county and State of New York, have invented a certain new and useful Tmprovement in Cushionlnsoles, of which the following is a full, clear, and exact specification.

This invention relates to a class of devices adapted to be used in conjunction with footwear.

My invention has for itsobject primarily to provide an insole designed to be employed interiorly-of the shoe, and other forms of the footwear of persons whereby the arch, or shank of the we arers foot may be comfortably supported in the shoe as well as tending to cause the pressure to be directed centrally of the foot when the person is walking, and the insole also being of a form serving to fill-out the portion of theupper of the shoe above the shank of its sole so that the shoe will fit snugly as this part of ordinary makessof shoes .are invariably cut so full that the wearer frequently suifers considerable discomfiture.

The invention consists essentially of a flexible bottom member, or layer of a shape conforming with the shape of the inner surface of the sole of the shoe, and on this bottom layer is a top flexible member, or layer formed with a substantially semi-elliptic projecting portion overhanging the shank part of the bottom layer. Between the layers of the insole is an approximately elliptic resilient pad which also overhangs the shank part of the bottom layer, and the top surface of-thispad is in contact with the underside of the overhanging portion of the top layer to serve as a cushion for the arch of a persons foot.

Another object of the invention is to bevel the edge of the pad under the overhanging portion inwardly toward the bottom layer so as to conform with the part of the upper of the shoe above the shank of the sole:

A further object of the invention is to provide a cushion insole which may be made in any shape and size for use in conjunction with footwear of various shapes and sizes.

A practlcal embodiment of the invention is represented in the accompanying drawing forming a part of this specification in which similar characters. of reference indicate cor.

responding parts in all the views, the said invention being more fully described herein- Specification of Letters Patent.

after, and then pointed out in the claim at the end of the description.

Tn the drawing, Figure 1 is a fragmentary view, showing a persons foot disposed in a shoe with one form of cushion insole em.- bodying my invention applied thereto. Fig. 2 is an enlarged top plan of the insole. Fig. 3 is an enlarged inverted plan of the insole, and Fig. 4 is a section taken on the line IV-TV of Fig. 2.

The cushion insole has a bottom member, or layer 10 which may be made of leather, or any other flexible material, and this layer is formed so as to conform with the shape of the inner surface of the sole, as 11, of a shoe, as 12,0r a boot, or other type of foot wear made to be worn by a person, though the shank part 13 of the bottom layer may be formed somewhat narrower in width than the shank of the sole of the shoe.

the shank part 13 of the bottom layer 10, and

part of the edges of the top layer and bottom layer may be secured by stitching, as at 1.7, or byany other means, in order to providea pocket 18 between the opposed shank por tions of the bottom and top layers.

Disposed in the pocket 18 between the flexible bottom layer 10 and the flexible top layer 1 1 is a pad 19 which may be made of rubber, or other resilient material to serve as a cushion for the arch, or shank portion of a persons foot. The cushion, or pad 19 is approximately elliptic in shape. This pad is of a Width to extend from substantially midway of the shank portions of both layers of the insole to the free edge of the semi-elliptic projecting portion 15 of the top layer 14, and the pad is of a length similar to the lengths of the shank parts of the layers 10 and 14. The resilient pad will thereby contact with the underside of the semi-elliptic overhanging portion 15 of the top layer 14 so as to also overhang the shank part of the bottom layer 10. The top surface of the I 5 full that the wearer frequently suflers conresilient pad 19 is formed on an incline, as

20, from the free edge of its overhanging portion toward the opposite edge thereof, this second edge beingpreferably graduated to nothing, and the pad is secured in the pocket 18 by stitching, or otherwise fastening its graduated edge to the top and bottom layers of the insole, as at 21. As illustrated in Fig. 1, by forming'the resilient pad 19 in this manner the insole will serve when in use to comfortablysupport the arch of the foot 22 of a person as well as tending to cause the pressure to be directed centrally of the foot when the person is walking, and serving to fill-out the portion of the upper of the shoe above theshank of its solo. The edge of the cush'ion, or pad 19 under the semi-elliptic portion 15 of the top layer 14 is beveled in-- wardly,as at 23,'to-ward the bottom layer 10 of theinsole, thus forming a flexible side portion capable of Joending upwardly and readily following the contour of the shoe upper when lacing the'shoe, to draw the proj'ecting portion of the padinto firm contact with the inner sideof the arch above the shoe sole, thus supporting the arch both on the bottom thereof and at the inner side, where there is always a loose play between the shoe and the foot, and positively preventing all sagging of the arch. Thebevel edge 23 of the pad will then causethis part of the shoe to fit snugly as Well as producing a neat ap pearance to the shoe as this part of the ordinary makes'of shoes are invariably cut so 'siderable discomfiture.

In the foregoing description, I have embodied the preferred form of my invention,

' but I do not Wish to be .understood as limiting myself thereto, as Iam' aware that modi- )artin" from the rinci 1e or sacrificin an b P a a of the advantages of this invention, therefore I reserve to myself the right to make such changes as fairly fall Within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In acushion insole for footwear, a flexible bottom layer of a shape conforming to the shape of the inner surface of the sole of the footwear, a flexible top layer on the bottom layer having an uninterrupted upper surface and formed with a substantially semi-elliptic projection overhanging the shank part of the bottom layer, and parts of both of'the layers being connected together but having free outer edges, thereby providing an open pocket between the shank parts thereof, and

' the interior of the shoe adjacent the-inner side of the wearers arch, substantially as set forth and for the purpose specified.

, This specification signed and witnessed this nineteenth day of October A. D. 1915.
